ABSTRACT

Disclosed is an adductor and sphincter reinforcing exercising device which can provide both linear movement for sliding foot plates leftward and rightward on a body and rotation of the foot plates, allowing a user to twist his or her legs in the process of widening and narrowing the legs to exercise the adductor and sphincter at the same time.

TECHNICAL FIELD

The present invention relates to an adductor and sphincter reinforcing exercising device which can provide both linear movement for sliding foot plates leftward and rightward on a body and rotational movement for rotating the foot plates, allowing a user to twist his or her legs in the process of widening and narrowing the legs to exercise the adductor and sphincter at the same time.

BACKGROUND ART

Adductors of modern men corresponding to muscles inside thighs are weakened due to lower body obesity caused by excessive nutrition, the sitting culture, or lack of exercises, causing deformed legs, distortion of pelvises, and the like. The deformed legs and distortion of pelvises are treated by a correction method, and clinics for their corrections are increasing.

In addition, the sphincter corresponding to the muscles surrounding tubular organs (the anal and the urethra) to regulate discharge is weakened due to aging, lack of exercises, and in particular, pregnancy and childbirth in the case of women. The degrading of the function of the sphincter of a human body causes urinary incontinence or fecal incontinence as the sphincter is not normally contracted or relaxed while he or she exercises or laughs.

Thus, according to the related art, separate exercising mechanisms are distributed to exercise the adductor and the sphincter. The muscles of the adductor may be reinforced by using an exercising device generally provided in a fitness center to push both the legs from a center to opposite sides or gather the legs at the center, and the sphincter is exercised through rotation of feet, in which case the device is relatively simple and is widely used at home.

Korean Patent No. 10-0405954 discloses a sphincter. As illustrated in FIG. 1, a pair of hingedly rotated foot plates 2 is coupled to upper portions of a body 1, and the sphincter is exercised due to twist thereof by taking the front side of the feet of a user and rotating the heels leftward and rightward.

In addition, Korean Utility Model No. 20-0397823 discloses a sphincter exercising apparatus. As illustrated in FIG. 2, the apparatus includes foot plates 4 hingedly rotated at upper portions of a base plate 3, and a rotating force regulating unit 5 is installed at a side surface of the body to regulate a degree by which it contacts the hinge, making it possible to regulate a rotating force of the foot plates.

However, according to the related art, the devices for exercising the adductor has a large volume, and thus are not suitable for home. Further, as the sphincter exercising devices rotate only the heels of the feet, it is suitable for domestic exercise of the sphincter but a movement width there of to a side is narrow, making it difficult to exercise the adductor.

Thus, exercising devices for individual portions need to be purchased all to exercise the sphincter and the adductor, resulting in a restriction in the economical factor and installation space at home. Thus, a new exercising device needs to be developed to solve the problem

DISCLOSURE Technical Problem

Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide an adductor and sphincter reinforcing complex exercising device which can slide foot plates themselves to opposite sides while providing a rotating force to the foot plates, exercising the sphincter and the adductor at the same time.

As a unit for moving the foot plates to sides, circular gears and a rack gear are installed in the foot plates and the body, respectively, to move the foot plates to sides by using a force by which the feet of a user is fastened.

As a unit for moving the foot plates to sides, opposite sides of the body of the exercising device adjacent to the two foot plate are connected to each other by a spring, and a central connecting wire connects the two foot plates so that if a user rotates the foot plates inward, the central connecting wire is wound on the foot plates and the foot plates themselves are slid inward, and if a rotating force applied to the foot plates by the user is removed, the foot plates are widened to opposite sides by a restoring force of the spring.

As a unit for moving the foot plates to sides, rotary plates are formed in connecting shafts of the two foot plates mounted to be slid laterally, the rotary plates and the body are connected to each other by a connecting member so that the foot plates are slid leftward and rightward according to a rotation degree of the rotary plates to regulate an interval between the two foot plates, or eccentric rotary plates are formed in the connecting shafts of the two foot plates and fixed shafts are formed in the body so that portions where the eccentric rotary plates and the fixed shafts contact are made different according to a rotation degree of the foot plates, whereby an interval between the two foot plates are regulated, and if a rotating force is removed, the foot plates are returned to their locations by the returning unit.

BEST MODE MODE FOR INVENTION

Hereinafter, the present invention will be described in more detail with reference to accompanying drawings.

FIG. 3 is a perspective view illustrating a complex exercising device according to the first embodiment of the present invention. FIGS. 4 to 5B are a plan view and sectional views schematically illustrating the complex exercising device according to the first embodiment of the present invention.

As illustrated, an adductor and sphincter reinforcing complex exercising device 10 according to the present invention includes a body 20 formed to be long laterally, and a foot plate 30 located on an upper surface of the body 20 and configured to be moved to opposite sides by a predetermined distance according to a rotation and a rotation ratio thereof.

The body 20 has a lower body plate 21 and an upper cover plate 22 to define an accommodating space 24 therein, and a sliding groove 23 is formed on an upper surface of the body cover plate to be long leftward and rightward.

A rack gear 25 and a support groove 26 are formed in the accommodating space. The rack gear is formed at one or both of front and rear walls defining the accommodating space in a transverse lengthwise direction of the body, and the support groove is formed on a bottom surface 241 of the accommodating space to be long to opposite sides. The support groove 26 may be a step formed to opposite sides, in addition to a form of a groove, and in the case of a step, a step surface may be formed to face the rack gear.

A pair of foot plates 30 is disposed on an upper surface of the body. Each of the foot plates may be configured such that a groove for inserting a foot of a user is formed on an upper surface thereof or a catching member protrudes from a side surface thereof so that, when the user twists his or her feet, a rotating force thereof may be transferred to the foot plate. It is apparent that, in addition to the above method, various formed may be provided, for example, by installing a belt or forming a shoe shape such that the foot plate may be worn.

A connecting bar 31 may protrude from a bottom surface of the foot plate. A lower end of the connecting bar is inserted into the sliding groove 23 formed in the body cover plate to be located within the body accommodating space 24, and is integrally coupled to a foot plate gear 40 which will be described below. Here, the connecting bar is formed in a cylindrical shape to contact a side wall of the sliding groove to guide a lateral movement of the foot plate when the foot plate is reciprocally rotated laterally along the sliding groove.

A foot plate gear 40 is coupled to the foot plate through a connecting bar. The foot plate gear is integrally coupled to an end of the connecting bar of the foot plate to be rotated together with the foot plate gear when the foot plate is rotated. A thread formed on an outer peripheral surface of the foot plate gear to form a circular gear is engaged with a rack gear 25 formed on a wall surface of the body accommodating space.

In this case, as illustrated, the connecting bar 31 for regulating an interval between the foot plate and the foot plate gear may protrude from an upper surface of the foot plate gear in addition to a shape protruding from a bottom surface of the foot plate, and a length of the connecting bar may be formed long such that the foot plate is spaced apart from an upper surface of the body not to contact the body, making it possible to minimize rotational friction of the foot plate.

The thread of the foot plate gear may be formed at an angle biased to one side so that a strong force may be transferred when the two foot plates gather at a center of the body.

A support 50 may be coupled to the foot plate gear. The support is rotatably hinge-coupled to a bottom surface of the foot plate gear via a hinge shaft 51, and is inserted into a support groove 26 in the body accommodating space to be slid to one side. The support linearly guides the rotated foot plate to opposite sides, and prevents the foot plate gear 40 from being spaced apart from the rack gear 25 at the same time. As illustrated, the support may be variously formed in a cylindrical shape in addition to a hexahedral shape.

Only one of the two ends of the hinge shaft 51 connecting the support and the foot plate gear is integrally coupled to the two members and an opposite end thereof is rotatably coupled, or both the ends thereof may be rotatably coupled. Then, the hinge shaft, the support, and/or the foot plate gear are coupled to each other through a bearing to minimize friction due to rotation thereof.

Referring to FIG. 6, a plurality of ball rails 52 may be installed even on a bottom surface of the support 50 contacting the support groove 26. The ball rails minimize a contact area between the support and the support groove to allow the support 50 to be easily moved to the left and right sides. As illustrated, the ball rails may be installed on a side surface of the support in addition to the bottom surface thereof, that is, on a surface contacting a side wall of the support groove.

A resilient body is installed in the exercising device of the present invention to locate both the foot plates at opposite sides of the body when a fastening force is not applied to the foot plates. Examples of the resilient body may be various springs such as a tensile spring, a compression spring, a spiral spring, an elastic band, and the like.

FIG. 7 is a schematic plan view illustrating an example of installing a tensile spring 60 a as a resilient body of the complex exercising device according to the first embodiment of the present invention.

As illustrated, the tensile spring connects one surface of the support 50 to one of opposite inner surfaces of the body close thereto. That is, one end of the tensile spring is coupled to an interior of a side surface of the body, and an opposite end thereof is coupled to a support surface opposite to the side surface of the body, so that a resilient force of the tensile spring pulls the support to opposite sides of the body.

Thus, if a user applies a force so that the two foot plates 30 gather at a center thereof while being rotated, the foot plate gear 40 is moved along the rack gear 25 so that a distance between the two plates becomes narrow. Then, the tensile spring 60 a is resiliently deformed by a force applied by the user to allow the foot plate gears to be moved, and if a force applied by the user is weaker than the resilient force, the foot plates are moved to opposite sides of the body by the resilient restoring force of the tensile spring.

FIG. 8 is a schematic plan view illustrating an example of installing a compression spring 60 b as a resilient body of the complex exercising device according to the first embodiment of the present invention.

As illustrated, the two supports 50 rotatably coupled to the two foot plates are connected by the compression spring 60 b, and the compression spring applies a resilient force in a direction resisting an interval between the two supports which becomes narrower to locate the two fool plates to opposite sides of the body.

As illustrated, opposite ends of the compression spring may be rotatably coupled to the connecting bars connecting the foot plates and the foot plate gears, in addition to a method of coupling the compression spring to the two supports.

FIGS. 9A and 9B are schematic plan views illustrating an example of installing a spiral spring 60 c as a resilient body of the complex exercising device according to the first embodiment of the present invention.

Referring to FIG. 9A, the foot plate gear 40 is installed integrally with the hinge shaft 51, and an end of the hinge shaft is rotatably coupled to the support 50 via a bearing. An upper side of the bearing of the support 50 is spaced apart from an outer wall of the hinge shaft by a predetermined width, and the spiral spring 60 c is installed in the spaced space. One end of the spiral spring 60 c is coupled to the rotated hinge shaft 51, and an opposite end thereof is coupled to the fixed support 50. In this case, if the user rotates the foot plate, the foot plate gear 40 integrally coupled to the foot plate and the hinge shaft 51 are simultaneously rotated to wind the spiral spring 60 c, and if a foot plate rotating force by the user is removed, the foot plate gear rotated by the resilient restoring force of the spiral spring moves the foot plate to opposite sides of the body due to an operation with the rack gear.

Referring to FIG. 9B, the hinge shaft 51 and the support 50 are integrally formed with each other, and an upper end of the hinge shaft is rotatably coupled to a bottom surface of the foot plate gear 40 via a bearing. A lower side of the bearing which corresponds to a bottoms surface of the foot plate gear is spaced from a groove of the foot plate gear by a predetermined distance, and the spiral spring 60 c is installed in the spaced space. One end of the spiral spring 60 c is coupled to the rotated foot plate gear 40, and an opposite end thereof is coupled to the fixed hinge shaft 51. In this case, if the user rotates the foot plate, the foot plate gear 40 integrally coupled to the foot plate is rotated to wind the spiral spring 60 c, and if a foot plate rotating force by the user is removed, the foot plate gear rotated by the resilient restoring force moves the foot plate to opposite sides of the body due to an operation with the rack gear.

A bottom surface of the body accommodating space may be inclinedly formed without using the resilient spring, so that the foot plate may be located to opposite sides of the body due to a self-weight thereof.

Referring to FIG. 10, the bottom surface of the accommodating space is formed to have an inclined surface 242 when a center between the two plates is a maximum point and opposite sides thereof are bottom points, so that the foot plate gears integrally rotated with the foot plates when the foot plates are rotated may ascend or descend along the inclined surface on the rack gears.

In the above-configured adductor and sphincter reinforcing complex exercising device of the present invention, if a user positions both the feet on the foot plates located at opposite sides of the body of the exercising device and then rotates the foot plates to gather the foot plates at a center of the body, a rotation and a linear movement are simultaneously applied, maximizing a adductor reinforcing effect and reinforcing the sphincter at the same time.

Meanwhile, FIG. 11 is a plan view illustrating a complex exercising device according to the second embodiment of the present invention. FIGS. 12A and 12B are sectional views schematically illustrating the complex exercising device according to the second embodiment of the present invention. FIGS. 13 a and 13B are schematic sectional views illustrating a foot plate having a stopper according to the second embodiment of the present invention. FIGS. 14A to 17 are schematic views illustrating various embodiments of a returning unit according to the second embodiment of the present invention.

Referring to FIG. 11, the foot plates 30, 30 a, and 30 b positioned on the body 20 are reciprocally moved laterally along the sliding grove 23, and are rotated by themselves to be slid and rotated at the same time.

Then, the two foot plates 30, 30 a, and 30 b are connected to each other by a central connecting wire 50 a, such that if a rotating force is applied to the foot plates, the central connecting wire 50 a is wound to narrow an interval between the two foot plates while the foot plates are rotated, and if the rotating force applied to the foot plates is removed, an interval between the two foot plates is widened by a restoring unit so that the foot plates 30 return to opposite sides of the body 20.

Here, one end of the central connecting wire 50 a is fixed to a left side of the left foot plate 30 a of the two plates 30, and an opposite end thereof is fixed to a right side of the right foot plate 30 b after passing by front sides of the left foot plate and the right foot plate. Locations of the foot plates to which end of the central connecting wire 50 a are coupled may be varied according to an interval between the two foot plates and a diameter of the foot plates on which the central connecting wire is wound. In this way, if the feet of the user is positioned on the two foot plates 30 connected to each other by the central connecting wire 50 a and the heels of the feet gathers at a center of the body, the left foot plate 30 a is rotated leftward and the right foot plate 30 b is rotated rightward so that the central connecting wire 50 a is wound on the two foot plates to narrow an interval between the two foot plates.

Referring to FIGS. 12A and 12B, a support groove 26 is formed long leftward and rightward on a bottom surface of the interior accommodating space 24 in addition to a sliding groove 23 formed on an upper surface of the body 20.

The foot plate 30 positioned on the body is located in the accommodating space 24 which corresponds to an interior of the body by protruding a connecting bar 31 from the bottom surface of the foot plate 30 and passing a lower end of the connecting bar through the sliding groove 23. A winding wheel 33 having a large diameter is formed in the connecting bar 31 located in the accommodating space, and the winding wheel is formed in the connecting bar in an integral or separable form. A winding groove 331 is formed on an outer surface of the winding wheel so that the central connecting wire 50 a may be wound thereon, and the central connecting wire may be wound on the winding groove once or a plurality of times according to a diameter of the winding wheel.

The support 50 is rotatably coupled to a lower portion of the winding wheel 33, and a lower portion of the support is inserted into the body support groove 26 to be slid only laterally. That is, the support 50 is slid leftward and rightward along the body support groove 26, the foot plates 30 are rotatably hinge-coupled to an upper portion of the support, and an interval of the two plates 30 mounted to the body 20 may be regulated according to a degree by which the central connecting wire 50 a is wound, so that the sphincter and the adductor may be exercised in the process of rotating the foot plates and moving the foot plates leftward and rightward.

Here, in the support 50, a stopper 53 protrudes from one side of the bottom surface of the winding wheel 33 or the upper surface of the support, and a stopper groove 332 defining a rotation range of the stopper may be formed on an opposite surface of the winding wheel 33 where the stopper is not formed.

For example, Referring to FIGS. 13A and 13B, the stopper 53 is formed at one side of the upper surface of the support 50, and the stopper groove 332 is formed at a lower portion of the winding wheel of the foot plate opposite to the stopper by a predetermined angle to limit a rotation range of the foot plate 30. This is because if the foot plates 30 are rotated excessively, the connection directions of the central connecting wire 50 a connecting the two foot plate are located not at a front side of the two foot plates but at a rear side thereof, so that an interval of the two foot plates is prevented from failing to be regulated as the central connecting wire is not wound on the foot plates when the foot plates are rotated in a proper movement direction.

Next, a returning unit 60 for winding the central connecting wire 50 a and moving the two foot plates 30 having gathered at a center of the body 20 to opposite sides of the body 20 again is installed in the exercising device 10 of the present invention.

As an example, the returning unit may be realized by a tensile spring 60 a. Referring to FIG. 14A, the tensile spring 60 a connects one surface of the support 50 and one of opposite inner surfaces of the body close thereto. In this way, in the exercising device to which the tensile spring 60 a is mounted, if a user is positioned on the foot plates and applies a force so that the foot plates gather at a center of the body while applying a rotating force to the two foot plates 30, the central connecting wire 50 a is wound to narrow an interval between the two plates while the foot plates are rotated and moved laterally. Then, the tensile spring 60 a is resiliently deformed by the force applied to the user, and if the rotating force applied to the foot plates 30 is weaker than a resilient restoring force of the tensile spring, the foot plates are slid to opposite sides of the body 20 by the resilient restoring force.

Referring to FIG. 14B, the returning unit includes weight elevating members 62 installed at opposite sides of the body to elevatably position a weight 63, respectively, and a pulling wire 64 one end of which is coupled to the weight of the weight elevating member to elevate the weight and an opposite end of which is coupled to the support 50 of the accommodating space through a side surface of the body, whereby the support 50 may be pulled to a side of the body by the pulling wire due to the weight 63 and thus the foot plates installed in the support may return to opposite sides of the body.

The weight elevating member 62 has a frame structure which is not fallen down by the elevation of the weight 63 and a plurality of pulleys 65 for regulating the disposition location of the pulling wire 64 is installed to elevate the weight 63 directly vertically and pull the support body 50 horizontally with the pulling wire 64. One or a plurality of weights is mounted to the weight elevating member 62 to regulate a pulling force of the pulling wire, and the weight elevating member 62 and the body 20 may be integrally formed or may be separately formed.

In another example, a spiral method may be applied to the returning unit 60 for the two foot plates.

Referring to FIG. 15, a male screw 321 may be formed in the hinge shaft 32 which is a rotary shaft integrally formed with a lower portion of the winding wheel 33 and a female screw 54 may be formed in the support 50 coupled to the hinge shaft so that the foot plates 30 and the support 50 may be rotatably coupled through a spiral method.

Then, the spirals of the male screw 321 and the female screw 54 formed in the hinge shaft 32 and the support 50 may constitute a structure which is lowered due to a self-weight thereof when an external force is removed by lowering a rotating speed of the screws while being rotated along the spirals.

In the exercising device 10 to which the spiral method is applied, if a rotating force is applied to gather the two foot plates 30 at a center of the body, the foot plates 30 are rotated and raised along the spirals and gather at the center through winding of the central connecting wire 50 a. Further, if a rotating force of the foot plates 30 is removed, the foot plates 30 is lowered along the spirals due to gravity, and the wound central connecting wire 50 a is released so that the foot plates may be moved to opposite sides of the body.

In addition, the two foot plates 30 of the spiral method may be configured to automatically return to their original positions when an external force is removed, by connecting opposite inner surfaces of the body to return wires 61.

Referring to FIG. 16, the return wires 61 are coupled to the left foot plate 30 a and the right foot plate 30 b, respectively, and one end of each of them is coupled to the left foot plate 30 a or the right foot plate 30 b and an opposite end thereof is coupled to opposite surfaces of the body accommodating space 24 close thereto. For example, in describing a connection state of the return wires 61 when the foot plates 30 are located at opposite sides of the body 20, one end of the return wire 61 is fixed to the left side of the left foot plate 30 a and an opposite end of the return wire is coupled to the left side of the body accommodating space 24 after the return wire is sequentially wound to the rear side, right side, and front side of the left foot plate, and one end of the return wire 61 is fixed to the right side of the right foot plate 30 b and an opposite end of the return wire is coupled to the left side of the body accommodating space 24 after the return wire is sequentially wound to the rear side, left side, and front side of the right foot plate.

The return wire 61 is wound through the winding wheel 33 at a lower portion of the foot plate, and the central connecting wire 50 a may separate the winding positions from each other to prevent them from interfering with each other.

In the exercising device where the return wire 61 is installed, if the foot plates 30 are located at opposite sides of the body 20, the central connecting wire is released and the return wire 61 is wound. If a rotating force is applied to rotate the foot plates 30, the central connecting wire is wound on the foot plates 30 to narrow an interval between the two foot plates and the return wire 61 is released. In contrast, if a rotating force of the foot plates is removed, the foot plates 30 are lowered as the hinge shaft is rotated along the spiral of the support 50 due to a self-weight thereof or a load applied by a user. Then, the foot plates 30 are rotated while the return wire is wound thereon, an exposure length of the return wire becomes shorter so that the foot plates return to the opposite sides of the body.

As a returning unit 60 of the two foot plates 30, a bottom surface of the body accommodating space which the support 50 contacts to be slid is formed to be an inclined surface 242 so that the foot plates may return to the opposite sides of the body due to a self-weight.

Referring to FIG. 17, a central portion of the bottom plate of the body accommodating space between the two foot plates is a maximum point and the opposite sides thereof corresponding to bottom points are formed to be the inclined surface 242. Then, if the foot plates 30 are rotated, an interval between the two foot plates 30 are narrowed and the supports 50 are raised along the inclined surface 242 to gather at a center of the body while the central connecting wire 50 a is wound on the winding wheels of the foot plates. Further, if a rotating force is removed, the foot plates 30 are rotated while descending along the inclined surface 242 due to the gravity, and the central connecting wire 50 a wound on the foot plates due to a rotation thereof is released to allow the foot plates to return to opposite sides of the body so that the foot plates may be fastened again.

Meanwhile, FIGS. 18 to 20 are sectional views and a plan view schematically illustrating a complex exercising device according to the third embodiment of the present invention. FIG. 21 is a plan view illustrating an operation state of a main part illustrating a complex exercising device according to the fourth embodiment of the present invention. FIGS. 22 and 23 are a plan view and a sectional view of a main part illustrating a complex exercising device according to the fifth embodiment of the present invention.

Referring to FIGS. 18 and 20, a support groove 26 is formed long leftward and rightward on a bottom surface of the interior accommodating space 24, in addition to the sliding groove 23 formed on an upper surface of the body 20.

Connecting bars 31 protrude from the bottom surfaces of the foot plates 30, 30 a, and 30 b positioned on the body. The connecting bars 31 extend into the accommodating space 24 which corresponds to an interior of the body through the sliding groove 23, and disk-shaped rotary plates 34 are integrally formed in the connecting bars 31 located in the accommodating space to be rotated together with the foot plates 30, 30 a, and 30 b.

The support 50 is rotatably coupled to a lower end of the connecting bar 31. The support is entirely or partially inserted into the support groove 26 of the body to be slid laterally.

The rotary plate 34 and the body 20 are connected to each other by a rotation bar 70. That is, one end of the rotation bar 70 is rotatably coupled to a periphery of the rotary plate 34, and an opposite end of the rotation bar is rotatably coupled to the body 20. In this way, if the rotary plate slid leftward and rightward and the body 20 are connected to each other by the rotation bar 70, the coupling portions of opposite ends of the rotation bar 70 always maintains a predetermined interval by the length of the rotation bar 70.

As illustrating the connecting portions of the rotation bar 70, the rotary plate 34, and the body 20 may connect the rotary plate 34 and a portion of the body 20 between the left and right rotary plates, or, although not illustrated, may connect the outer body portions of the left and right rotary plates and the rotary plates, and may connect various locations of the body and the rotary plates.

In this configuration, if a rotating force is applied to the foot plates 30, the foot plates are rotated and the connecting bars 31 on the bottom surfaces of the foot plates are rotated together. Further, the rotary plates 34 integrally formed with the connecting bars are also rotated, and movement distances of the rotary plates are limited by the rotation bars.

That is, as illustrated in FIG. 20, the rotation of the rotary plates 34 to which a rotating force is applied counterclockwise is limited by the rotation bars 70, and thus the rotary plates 34 pull the rotation bars 70. Here, the rotation bars 70 are fixed hinge coupling parts and the rotary plates may be slid leftward and rightward, and thus a pulling force applied to the rotation bar 70 is transferred to the rotary plates 34 to narrow an interval between the two rotary plates and gather the rotary plate at a center of the body.

Thus, if clockwise or counterclockwise rotating forces are applied to the two foot plates 30 in opposite directions, the two spaced foot plates 30 are slid to a center of the body while the heels of a user gather and thus an interval between the foot plates 30 is narrowed, allowing the sphincter and the adductor to be exercised.

In addition, a returning unit for returning the foot plates 30 having gathered at a center of the body to opposite sides of the body which is original positions is installed in the complex exercising device 10. Various known technologies may be applied to the returning unit, for example, by connecting opposite sides of the interior of the body adjacent to the support to each other by the tensile spring 60 a to return by resilient restoring force, installing a weight pulling the support to opposite sides, or inclining the body bottom surface and moving the foot plates to opposite sides of the body due to the self-weight when an external force is removed.

Meanwhile, referring to FIG. 21, two rotation bars 70 are fixedly coupled to the left and right rotary plates 34 in a direction perpendicular to the connecting bars, and the two rotation bars are hinge-coupled to opposite ends of the connecting member 80, respectively.

If an external force is not applied to the foot plates 30, the foot plates are located at opposite sides of the body 20, and if a rotating force is applied, the two foot plates gather at a center of the body.

For example, in describing an operation state of the left rotary plate 34, if a rotating force is applied to the foot plate counterclockwise, the rotary plate 34 integrally formed with the foot plate is also rotated counterclockwise. Further, the rotation bar 70 coupled to the rotary plate is also rotated about a connecting shaft of the rotary plate. Here, rotation of the rotation bar is limited by the connecting member, and thus finally the integrally formed rotation bar and rotary plate are rotated counterclockwise about a coupling portion of the connecting member and the rotation bar.

Then, the rotary plate 34 is rotatably coupled to the lower support 50 to be moved only leftward and rightward, and thus a forward and rearward movement component applied to the rotation of the rotation bar and the rotary plate is transferred to the connecting member 80 so that the connecting member is moved to a lower side or an upper side.

That is, if the foot plate 30 is rotated counterclockwise, the rotary plate 34 and the rotation bar 70 generate a leftward, rightward, forward, and rearward movement component while being rotated through a coupling portion with the connecting member 80, in which case the leftward and rightward movement component is transferred to the rotary plate to slide the foot plate leftward and rightward and the forward and rearward movement component is transferred to the connecting member 80 to move the connecting member forward and rearward.

Although not illustrated, a unit for limiting a leftward and rightward movement of the connecting member 80 may be further installed. With the leftward and rightward movement limiting unit, the connecting member can be prevented from being biased and moved to one side, by protruding one side of the connecting member, and forming a groove forward and rearward on an inner surface of the body so that the protruding portion can be inserted thereinto so that the protruding portion is moved only forward and rearward along the groove and the leftward and rightward movement thereof is limited.

Meanwhile, referring to FIGS. 22 and 23, the complex exercising device 10 includes an eccentric rotary plate 35 where the connecting bar 31 is eccentric to one side instead of the rotary plate of the preceding embodiment where the connecting bar is formed at a center of the body, and a fixed shaft 27 is formed in the body 20 to contact an outer surface of the eccentric rotary plate. The fixed shaft 27 protrudes from an inner surface of the body accommodating space 24 such as a bottom surface, an upper surface, or a side surface of the body accommodating space 24, or protrudes from a body surface at an outer side of the eccentric rotary plate to form a step in addition to a cylindrical form to support an outer surface of the eccentric rotary plate through various methods.

The eccentric rotary plate 35 is prejudiced to one side, and gradually spaces the connecting bar 31 and the fixed shaft 27 apart from each other at a larger interval as compared with a case where an interval radio between the connecting bar 31 and an outer surface of the eccentric rotary plate 35 further increases to achieve eccentricity.

The fixed shafts 27 are formed at outer sides of the two connecting bars 31 so that the two connecting bars are pushed inward during rotation of the foot plates. That is, the fixed shafts 27 are located close to the connecting bars 31 and are formed to contact the outer sides of the two connecting bars, whereby the connecting bars are pushed from the fixed shaft by the eccentric rotary plates during rotation of the foot plates so that the fixed shafts 27 gather between the two connecting bars.

In contrast, although not illustrated, if the fixed shafts are formed on the inner sides of the two connecting bars, the connecting bars are moved to opposite sides while the fixed shafts and the connecting bars become far away from each other by the eccentric rotary plates during rotation of the foot plates, while providing a different exercising effect.

As described above, in describing an operation state of the complex exercising device including the eccentric rotary plates 35 and the fixed shafts 27 contacting outer surfaces of the eccentric rotary plates, if a user places both the feet on the left and right foot plates 30, 30 a, and 30 b and gathers the feet while rotating the foot plates so that only the heels may become close to each other, a rotating force is applied to the foot plates 30, and the connecting bars 31 under the foot plates are also rotated, whereby the eccentric rotary plates 35 integrally coupled to the connecting bars are rotated in the same direction as that of the foot plates.

For example, referring to FIG. 23, as a rotating force is applied to the left foot plate 30 a counterclockwise, the eccentric rotary plate 35 is also rotated counterclockwise. Then, as a distance between the outer surface of the eccentric rotary plate 35 adjacent to the connecting shaft 27 and the connecting bar 31 gradually becomes larger, the eccentric rotary plate 35 pushes and moves the slidably mounted foot plate 30. Thus, the two foot plates 30, 30 a, and 30 b are rotated and is slid leftward and rightward at the same time to be gathered at a center of the body, and when a rotating force is removed, the foot plates are moved to opposite sides of the body by the returning unit to allow repeated movements, thereby making it possible to reinforce the sphincter and the adductor.
